Non-Abelian Chern-Simons Actions in Three-dimensional Projective Superspaces
Masato Arai, Shin Sasaki
We construct an action for the superconformal Chern-Simons theory with non-Abelian gauge groups in three-dimensional N=3 projective superspace. We propose a Lagrangian given by the…
Worldsheet Description of Exotic Five-brane with Two Gauged Isometries
Tetsuji Kimura, Shin Sasaki
We study the string worldsheet description of the background geometry of the exotic -brane where two isometries are gauged. This is an extension of the gauged linear sigma m…
A Thermal Field Theory with Non-uniform Chemical Potential
Masato Arai, Yoshishige Kobayashi, Shin Sasaki
We investigate thermal one-loop effective potentials in multi-flavor models with chemical potentials. We study four-dimensional models in which each flavor have different global U(…
Twisted N=4 Super Yang-Mills Theory in Omega-background
Katsushi Ito, Hiroaki Nakajima, Shin Sasaki
We study the twisted N=4 super Yang-Mills theories in the Omega-background with the constant R-symmetry Wilson line gauge field. Based on the classification of topological twists o…
Worldsheet Instanton Corrections to 522-brane Geometry
Tetsuji Kimura, Shin Sasaki
We study worldsheet instanton corrections to the exotic 522-brane geometry in type II string theory. The BPS vortices in the N=(4,4) gauged linear sigma model modify the geometry o…
Gauged Linear Sigma Model for Exotic Five-brane
Tetsuji Kimura, Shin Sasaki
We study an N=(4,4) supersymmetric gauged linear sigma model which gives rise to the nonlinear sigma model for multi-centered KK-monopoles. We find a new T-duality transformation o…
